Keywords in C#

A keyword is a sequence of characters, such as identifiers, but it is used as reserved by the C# compiler except that it can be used as the identifier when prefixed with the @ character.
The C# language does support the @ character to prefix a variable name, but it is not common practice to use it. Listing 1-3 shows the usage of the keywords in a method.

Listing 1-3. Example of the Keywords

Code Snippet
  1. static void Main(string[] args)
  2. {
  3.     int a = 100, @int = 100;            /* int is keyword and @int used
  4.                                          * as identifier */
  5.     try {                               /* try is keyword */
  6.   Console.Write(a / @int);
  7.     }
  8.     catch {
  9.    throw;
  10.     }                            /* catch and throw is keyword */
  11. }
